Cipher Peons are the main foot soldiers of Cipher and appear in Pokémon Colosseum. Much like the "Grunts" of other criminal groups, Peons will impede on the player's progress by blocking important areas or by dropping from the ceiling to ambush intruders. Many Peons also have Shadow Pokémon, which must be weakened and Snagged away from them.

The standard uniform of a Cipher Peon is a single bodysuit fashioned with a distinctive visored helmet. Male Peons wear a navy-blue uniform and a bandanna around their neck, while female Peons wear purple and leg-length boots. A few Peons have customized uniforms, usually to reflect higher importance within the Cipher ranks.
